WebMar 10, 2010 · Hourglassing and ALE. Permalink Submitted by Andras Nelhiebel on Sun, 2010-03-14 18:25. Hello Amiratrian! ALE: it is a mixture of Lagrangian and Eulerian discretization. Lagrangian is when the mesh deforms with the matertial, and Eulerian is when you have a fixed mesh in the space, adn the material flows from one cell to another.
